php: using DomDocument whenever I try to write UTF-8 it writes the hexadecimal notation of it

Question

When I try to write UTF-8 Strings into an XML file using DomDocument it actually writes the hexadecimal notation of the string instead of the string itself.

for exam

Answer 1

Apparently passing the documentElement as $node to saveXML works around this, although I can't say I understand why.

e.g.

$dom->saveXML($dom->documentElement);

rather than:

$dom->saveXML();
